#### Graphical Representation of Compounds

**Compound I:**
![Compound I](URL_to_image)
\[ \mathrm{-C(=O)-\textit{O}-\textit{group}} \]

**Compound II:**
![Compound II](URL_to_image)
\[ \mathrm{-C(=O)-\textit{N}-\textit{group}} \]

**Compound III:**
![Compound III](URL_to_image)
\[ \mathrm{-\textit{N}-\textit{group}} \]

**Compound IV:**
![Compound IV](URL_to_image)
\[ \mathrm{-C\equiv \textit{N} \textit{group}} \]

**Compound V:**

#### Detailed Explanation:

An **amide functional group** is characterized by a carbonyl group (C=O) attached to a nitrogen atom (N). In the list provided, you can identify which compounds have this structural feature to determine those that contain amide functional groups.

- **Compound I** shows a carbonyl group (C=O) attached to an -O- group, indicating it is an ester, not an amide.
- **Compound II** features a carbonyl group (C=O) attached to a nitrogen (N), which is characteristic of an amide.
- **Compound III** contains a nitrogen attached to other substituents without a carbonyl, indicating it is an amine, not an amide.
- **Compound IV** has a nitrile group (C≡N) and does not fit the amide criteria.
- **Compound V** contains a carbonyl group (C=O) attached to an -OH group, identifying it as a carboxylic acid, not an amide.

Thus, **Compound II** is the only one that contains an amide functional group.

**Correct Answer:** Option II
